Answer:
2.3 dollars
Step-by-step explanation:
Given:
Ratio table that shows the costs for different amounts of bird seed
To find: the unit rate in dollars per pound
Solution:
Amount (pounds) 5 10 15 20
Cost (dollars) 11.5 23 34.50 46
Here,
![\frac{5}{11.5}=\frac{50}{115}=\frac{10}{23}\\\\\frac{10}{23}=\frac{10}{23}\\\\\frac{15}{34.50}=\frac{1500}{3450}=\frac{150}{345}=\frac{30}{69}=\frac{10}{23}\\\\\frac{20}{46}=\frac{10}{23}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B11.5%7D%3D%5Cfrac%7B50%7D%7B115%7D%3D%5Cfrac%7B10%7D%7B23%7D%5C%5C%5C%5C%5Cfrac%7B10%7D%7B23%7D%3D%5Cfrac%7B10%7D%7B23%7D%5C%5C%5C%5C%5Cfrac%7B15%7D%7B34.50%7D%3D%5Cfrac%7B1500%7D%7B3450%7D%3D%5Cfrac%7B150%7D%7B345%7D%3D%5Cfrac%7B30%7D%7B69%7D%3D%5Cfrac%7B10%7D%7B23%7D%5C%5C%5C%5C%5Cfrac%7B20%7D%7B46%7D%3D%5Cfrac%7B10%7D%7B23%7D)
Therefore,
![\frac{5}{11.5}=\frac{10}{23}=\frac{15}{34.50}=\frac{20}{46}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B11.5%7D%3D%5Cfrac%7B10%7D%7B23%7D%3D%5Cfrac%7B15%7D%7B34.50%7D%3D%5Cfrac%7B20%7D%7B46%7D)
Cost of 10 pounds = 23 dollars
So, cost of 1 pound =
dollars
